Speecation of Letters Patent.

Application filed April 3, 1905. Serial No. 253,661.

T0 a/ZZ whom it may concern;

Be it known that I, TnoMAs W. DoNAHoo, a citizen of the United States, residing at Tishomingo, Chickasaw Nation, Indian Territory, have invented certain new and useful Improvements in King-Bolts; and I do declare the following to be a full, clear, and exact description oiE the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in casings or boxings for the king -bolts of wagons and other vehicles.

The object of the inventibn is to provide a simple and inexpensive device of this characterwhich will protect the bolster and sandboard against wear and the king-bolt against breakage, thereby materially prolonging the lives of these parts.

With the above and other objects in view the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed'out in the appended claim.

In the accompanying drawin s, Figure l is4 a side elevation of a bolster an sand-board, showing the application of my invention thereto. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical longitudinal sectional view, and Fig. 4 is a vertical transverse sectional view.

Referring to the drawings by numeral, 1 denotes a sand-board, and 2 a bolster which is disposed. above the sand-board and connected thereto by a king-bolt 3. The bolster and sand-board have upon their opposing inner faces metallic wear-plates 5 and 6, which form the lilith-wheel of the wagon or other vehicle to which the device is applied. These plates 5 and 6 are substantially rectangular in iorm and are secured in place by bolts, 4 rivets, or other suitable fastening means 7. The bearing or wear plate 5 upon the under side of the bolster is secured to the lower end of a cylindrical sleeve or boxing 8, which extends centrally through said bolster. This sleeve or boxing 1s provided for the reception of the king-bolt 3, and its upper end is formed with an outwardly-extending annular 'flange 9, which is countersunk in the top of the bolster, so that its upper surface lies flush with the upper surface oi? said bolster. Within the I'lange 9 at the upper end of the said sleeve is an annular groove or recess, which is adaptedto receive the head 1l of the kingbolt 3. This circular head ol? the king-bolt 'lits within the groove or recess and lies flush with the upper' surface of the bolster. Secured to the lower bearing or wear plate 6 upon the sand-board l is a cylindrical sleeve or boxing 13, which extends through the sand-board, as shown, and is adapted to receive the lower portion of the king-bolt.

The construction, use, and advantages of the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that the sleeves orboxings and the wear-plates prevent any wear of the bolster and sand-board and materially strengthen the same. It will also be noted that the device is ol simple and durable construction and may be applied to any wagon or vehicle at a comparatively small cost.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacriiicing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A bolster having a central vertical o ening,

a wear-plate on the lower side ofthe olster,4

and secured thereto, a boxing in the opening in the bolster, having its upper end'provided with an outwardly-projecting annular flange, countersunk in the bolster and provided with an internal countersink, the lower end of the boxing being secured to the' wearplate; a sand-board having a wear-plate on its upper side, secured thereto, a boxing extending through the center of the said board and having its upper end secured to the last-mentioned wear-plate, and a kingfbolt extending through and connecting the boxings and having a head at its upper end in the counter sink of the bolster-boxing, substantially as described.

In testimony whereof I have hereunto set"` my hand in presence of two subscribing witnesses.
